Hello All

I'm thinking of making a circuit which will monitor the traffic on an I2C bus,which links with a serial port on a PC.It's purpose to report in English what is being transfered between devices on the I2C bus

I.e.

Device 32H transfered 2 bytes to device at 40H the bytes were 02 40.etc.etc.

bit 7 at address 21H was set.

Hopefully you've got the general idea.Not wishing to re-invent the wheel has anyone else done this or can you suggest possible pitfalls with solutions.As a Serial port to PC will be slower than the I2C Bus.I was going to store the traffic in an 8K static ram,using a sort of round robin type FIFO.So that the output to the PC would catch up during periods of idleness on the I2C bus.

This is more of a can we.So haven't decided on variant of 8052 or static ram yet.

Thanks in advance for any comments,ideas whatever.
